alt Hacker NewsRussia didn’t react to his ouster by demanding a restoration of proper governance, they reacted by sending clandestine troops to seize Crimea in preparation for annexation the next month. Annexing other countries’ sovereign territory is a red line for good reason.
I'm not defending Russia here. Yanukovich was ousted for good reasons (and arguably he carried out a coup first when he reverted the country's constitution). My point is that, if we don't invade other countries only because their leadership does what we want, then we aren't really qualitatively any better.
